2. How to choose a better solution when choosing a 24V DC power supply?

There are many types of 24VDC power supplies on the market, but which one is best for your needs? When choosing a 24VDC power supply, the Switch Mode Power Supply (SMPS) is generally considered to be a better choice, especially in application scenarios that require high efficiency, stability and compact design.

What is a Switch Mode Power Supply (SMPS)? What are its advantages?

A switching power supply is a power supply device that converts electrical energy into the required voltage and current through high-frequency switching technology. Unlike traditional linear power supplies, SMPS uses pulse width modulation (PWM) technology to adjust the output voltage and current through fast switching, thereby achieving higher efficiency and smaller size.

The main advantages of SMPS include:

High efficiency: The conversion efficiency of SMPS is usually above 85%, and some high-end models can even reach 95%. In contrast, linear power supplies have large losses during the conversion process, especially when the load changes, and the energy waste is obvious.

Small size and light weight: Since switching mode power supply uses high-frequency switching technology, it can use smaller transformers and filters, which greatly reduces its size and weight, making it very suitable for applications that are sensitive to space and weight.

Strong output stability: SMPS can maintain a stable output voltage within a wide input voltage range, and can provide stable power support even in environments where the power supply voltage fluctuates greatly. This is especially important for scenarios that require stable power supply, such as industrial control and communication equipment.

Perfect protection function: Modern SMPS usually has a variety of built-in protection functions, such as overload protection, short circuit protection, over-temperature protection, etc., which can effectively prevent power failure from causing damage to the equipment.

Application scenarios of SMPS in 24- volt DC power supply

In the 24VDC power supply demand, SMPS is widely used in various industrial equipment, automation systems and high-precision electronic equipment. For example, in the application of embroidery machines, SMPS can provide continuous and stable power to motors and control systems to ensure accuracy and consistency during the embroidery process. Compared with traditional power supplies, SMPS is not only more efficient, but also can effectively reduce the impact of power supply fluctuations.

SMPS also performs well in the school's network laptop charging cabinet. It can provide stable 24V power output for multiple devices at the same time, avoiding unstable charging or device damage caused by voltage fluctuations. In addition, SMPS is also widely used in 3D printers and agricultural irrigation equipment to ensure that these devices can operate stably in different environments and conditions.

How to choose a suitable SMPS?

When choosing an SMPS, users need to consider the following key factors:

Power demand: Choose a suitable switched mode power supply according to the power demand of the device. For example, if your system requires a power of about 100W, it is more reasonable to choose an SMPS with a power between 120W-150W, which can provide enough margin for the device to avoid long-term full-load operation and cause the power supply to overheat.

Input voltage range: SMPS usually has a wide input voltage range (such as 90V-264V), which can adapt to the grid voltage in different regions around the world. Therefore, if your device needs to be used in different countries or regions, it is very important to choose an SMPS with multi-voltage input.

Output stability: Make sure that the selected SMPS has high-precision output voltage regulation capabilities, especially in scenarios with high requirements for power supply quality, such as precision instruments, medical equipment, etc. Stable voltage output can ensure the normal operation of the equipment.

In addition, durability and reliability are also important criteria for selecting SMPS. Choosing brands and models that have been verified by the market can ensure long-term stable operation and reduce the risk of equipment damage caused by power failure.
